[nengo-user] integrating Nengo with IPython

[Trevor Bekolay]

Hi Mehdi,

Unfortunately those instructions were for a version of the IPython notebook
which is at this point pretty old. IPython is easier to plug into now, so
it should be possible to update these instructions; but, the new version of
Nengo is implemented in Python, which works well with IPython out of the
box, so we haven't gone back and updated these instructions recently.

My suggestion for now is to just do what the javascript changes would have
done manually. So, somewhere at the top of your notebook, do

from stats.ipython import run_in_nengo

and then when you want to run a Nengo 1.4 script, do:

run_in_nengo('''  # Replace below with your Nengo script
    import nef
    net=nef.Network('Test')
    net.make('A',50,1)
    net.make_input('input',{0: -1, 0.2: -0.5, 0.4:0, 0.6:0.5, 0.8:1.0})
    net.connect('input','A')
    log=net.log()
    log.add('input',tau=0)
    log.add('A')
    net.run(1.0)
''')

The rest of that document should work from that point onwards.

Sorry about the Nengo 1.4 rough edges! We're hoping to get Nengo 2 out the
door soon, which should be much easier to interact with in the notebook!
